System Administration is a highly specialized field in the Information Technology (IT) sector. It involves a variety of tasks related to the maintenance, configuration, and reliable operation of computer systems, such as networks and core services. System Administrators not only manage the daily operations of these systems, but also have the responsibility of ensuring these systems are secure, protected from malicious attacks and software vulnerabilities.

A System Administrator is capable of optimizing system operations to ensure maximum uptime and efficiency using solutions like automation. This can help organizations save on costs and resources. An expert System Administrator can also identify areas where additional system resources are needed, create disaster recovery plans, automate processes, reduce risks, provide technical advice and implement overall security policies.

Some areas that should be addressed regularly by System Administrators include information security measures, disaster recovery solutions and infrastructure planning. All of this helps ensure that an organization's mission-critical systems remain up-and-running no matter what the situation may be.

Here's some projects that our expert System Administrator made real:

  • Setting up a secure backup process for companies
  • Troubleshooting login issues for laptops
  • Installing software for server control panels
  • Managing complex server configurations
  • Automating systems setup and configuration
  • Creating content for social media accounts
  • Enhancing availability, managing traffic and protecting from disasters
  • Debugging applications on Exchange Server
  • Scheduling data flows using SQL Server Agent
  • Restoring access to webpages

System Administration is an important job that requires expertise to master. With its complexity comes huge responsibilities - handling a controlled computing environment of a company or organization without compromising data security. If you have a project or idea that you want to be handled by an experienced System Administrator, Freelancer.com has you covered on finding one that meets your requirements.

    Transfer ArcGIS Pro License
    5 Hari left
    Terverifikasi

    My ArcGIS Pro 3.0 single-use license is still tied to a laptop that no longer boots, and Esri’s online licensing portal refuses to de-authorize it even after I followed the normal steps. I also don’t have access to an active Esri Customer Service account, so I can’t open a support ticket directly with them. I need someone familiar with Esri licensing workflows—especially the steps for reclaiming or transferring a locked-up single-use license—to walk me through (or, if possible, handle) the entire process so I can activate ArcGIS Pro 3.0 on my new Windows laptop. This may involve: • Verifying the license status in My Esri • Requesting a manual reset or entitlement transfer from Esri on my behalf • Guiding me through installation and success...

    Remove OneDrive & Clean C Drive

    I’m on Windows 11 and want Microsoft OneDrive completely gone—no lingering background services or registry traces. Once it is uninstalled and the sync folders are safely disconnected, I need a thorough audit of my C: drive. The goal is to identify and eliminate every duplicate across documents, photos, videos and any other file types, then reorganise what remains into a clearer folder structure. I’d like sensible, easy-to-navigate directories (e.g., Work, Personal, Media) and shortcuts updated so existing programs still find what they need. Please back up anything you delete or move, provide a log of duplicates removed, and deliver a concise before/after folder map so I can see exactly what changed. Tools such as PowerShell, WinMerge, dupeGuru, or comparable Windows 11 ...

    I need a Windows-focused developer who can turn XMRig into a background service for a fleet of mining PCs I already operate. The goal is simple: once the installer runs, XMRig should install the rig with the needed program, start automatically with the OS, and apply my custom CPU tuning without any visible console or tray icon. Key details • Target OS: Windows 10/11 on consumer-grade hardware • Required tweak: XMRig custom setup as it runs (no GPU work) • One-click or fully installer preferred (Inno, NSIS, or your tool of choice) Deliverables 1. Compiled XMRig binary with my CPU config baked in (or an editable JSON if you have a smarter approach) 2. installer/​script that registers the miner as a background service and confirms successful launch 3.

    I’m looking for a reliable local technician who can act as the hands-and-eyes extension of our remote IT team whenever a workstation issue crops up. The core of the role is simple: be on site, follow the real-time guidance of our engineers, and help us troubleshoot whatever is affecting the user’s desktop or laptop. Typical calls may involve tracing connectivity problems, reseating or replacing components, checking cabling, or running through software prompts that our remote tools can’t reach because the machine is unresponsive. While the immediate need centers on workstation troubleshooting, a bit of flexibility is appreciated—occasionally we might ask you to press the power button on a switch or confirm a status light on nearby gear if you’re already ther...
